Web application java

1.Create a simple "HelloWorld" servlet where the client html file has a button with name "Click me!" and the servlet gets executed on the click of button. The servlet displays html message: "Hello World! This is my first servlet!".

2.Create a servlet that accepts string data fields from the client html and converts all of them to upper case. E.g. First name, last name, country, subject. These fields are part of the request html. The values are received by the servlet, converted to upper case and sent back to client as part of response html

These two projects are to be done urgently.
It should work in ecplise.
